SketchAndCalc® is an irregular area calculator app for all manner of images containing irregular shapes. Uniquely, the area calculator is capable of accurately calculating irregular areas of uploaded images, photographs or plans quickly. Using the area calculators autoscale tool, you can set the ...
The areas (in acres) of some closed paths can always be determined. I measure a few of these and determine the scale factor for the particular graphic. Then I trace an unknown area-of-interest and apply the scale factor to get acreage value I want. So ...
If you want tocalculate the area of a rectangle, triangle, or circle in Excel, here is how you can do that. It is possible to calculate the area of those shapes when certain values such as length, height, or radius is already given. Calculate the area of a Rectangle in Excel The bas...
Calculate the volume of a cone (such as an ice cream cone), it allows multiple different types of inputs and outputs - depending on your need. Calculate the surface area of different geometrical shapes Calculate the area of a circle
The area of a sector –which is our lateral surface of a cone – is given by the formula: A(lateral) = (s * (arc length)) / 2 = (s * 2 * π * r) / 2 = π * r * s The formula can be obtained from proportion: ratio of the areas of the shapes is the same as rati...
Sometimes either or both of the shapes represented are too complicated to use basic area equations, such as an L-shape. In this case, break the shape down even further into recognizable shapes. For example, an L-shape could be broken down into two rectangles. Then add the two areas togeth...
Then, use our square footage calculator to find the area of your space’s shape. If you’ve divided a room into multiple shapes, remember to add up all of the shapes’ areas to find the room’s total area. Using our calculator’s “Add the new shape” button, you can easily input ...
Example: Simple Compound Shapes Finding the dimensions Example: Subtracting one area from another Example: Partial areas Example: Decisions! Combine? Subtract What is area? Area tells us the size of a shape or figure. It tells us the size of squares, rectangles, circles, triangles, other polygo...
Calculate the lateral and total surface areas of a prism whose height is 12 cm and whose base is a rectangle with dimensions 5 cm by 7 cm. What's the height of a rectangular prism if the surface area is 148 cm 2;, the width is 4 cm, ...
Calculate the area of each shape by using their respective formulas. Finally, add the areas of all the individual shapes to find the area of the irregular quadrilateral. As discussed earlier and as the name suggests, a parallelogram is a quadrilateral formed by two pairs of parallel lines with...
